All submission (.inp) and results (.odb) files for finite element models (FEMs) presented in the supplementary material of Mehari Abraha et al., (2021). All FEMs were built and solved using Abaqus v16 and v19 (Dassault Systèmes), thus .inp and .odb files can be viewed or solved using the Abaqus CAE user interface, or as a text file.

Submission (.inp) files contain all data and parameters relevant to FEM creation (3D geometry, material properties, muscle force loads and constraints, interface parameters) and FEM solution (solver settings and parallel processing parameters).

Results (.odb) files contain 3D geometries, and all nodal results (displacements, stresses and strains).

FEMs presented in the supplementary text included:-

1) human models of the healthy and fracture fixed mandible (angle fracture repaired with champy and biplanar fixation), loaded with forces and constraints simulating left and right side chews.

2) macaque models of the champy fixed mandible simulating left side chews with varying values for the coefficient of static friction at the bone-plate (BP), fracture plane/bone-bone (BB), miniplate-screw (IS) interfaces. The coefficient of static friction was varied from 0.1 - 0.5 for each interface (in 0.1 increments) while the other two were held constant (0.3).

Funding

Funding for the purchase and maintenance of the FEA and virtual reconstruction software was secured via internal funds by Monash University to Dr Olga Panagiotopoulou
